Printers often only support 2.4GHz Wi‑Fi or struggle with DFS channels on 5GHz. Start with band checks, then try WPS/manual SSID, or use Wi‑Fi Direct.
1) Verify Wi‑Fi band and SSID
- Legacy printers may not see 5GHz; use 2.4GHz SSID.
- Disable DFS channels; prefer channels 1/6/11 for 2.4GHz.
- Check for AP isolation and MAC filtering on the router.
2) Use WPS or manual SSID
- WPS: Press printer Wi‑Fi/WPS → press router WPS within 2 minutes.
3) Try Wi‑Fi Direct (ad‑hoc)
Enable Wi‑Fi Direct on the printer and join the temporary SSID from your device. Good for quick prints or initial setup.
4) Reserve a static IP
In your router, reserve the current printer IP to its MAC address. Prevents “Offline” after reboots.
Conclusion
Wi‑Fi setup issues are usually caused by incorrect passwords, band incompatibility, or router settings. Use WPS for quick setup, prefer 2.4 GHz for compatibility, set a static IP, and ensure your router allows printer connections. For persistent issues, consult your printer's manual or contact support.
